Essential goal - be ready at end of LS2 with full-function system ready for SPS Tests SPS upgrade after LS2 ( new injector, higher currents, new operational modes) We must use the demo system, MD time post LS1 to validate control ideas, validate kicker and technical approach. Full Function is only 1 design iteration away from Demo System

Near Term Research and Technology Plans

Existing 1 bunch Demo System

FY13 - FY14 Expand processing capabilities, add synchronization,

ther features (SLAC)

FY14 - FY15 Fabrication of wideband Transverse Kicker proof of principle prototype (CERN), upgrade Demo gateware (SLAC) FY15 - FY16 Tests of 1 bunch upgraded demo with wideband kicker

How is the "Full-Function Prototype" different from the "Demo System"? From a "Production System"?

Demo System -initial capabilities to explore single bunch dynamics, explore control algorithms,limited bandwidth kicker Upgraded Demo System - enhanced capability, to be used with proof of principle wideband kicker, validate control capabilities "Full-function" capability to control full ring, energy ramp, injection flexibility, operational interface "Production System" - final operational hardware, with necessary upgrades and modifications learned from running "Full-Function"

LARP June 13 Review - Budget Guidance and Planning towards 2020 Full Function System

June 2013 LARP funding guidance ($1.3M) used to plan and scale FY14,15,16 effort, with modest early use of FY17 project funds Expansion of 1 bunch Demo System

FY13 -14 Expand processing capabilities, add ramp synchronization, orbit offset dynamic range, other features (SLAC) FY13 -14 Fabrication of wideband Transverse Kicker proof of principle prototype (CERN) FY15 - 16 Beam Tests of 1 bunch demo with wideband kicker (both)

LARP Project funding expected start in 2017

Design and development of full-function system Requires joint LARP-CERN Resources to complete Wideband Feedback plans presented at LARP Internal Review June 2013 (www.uslarp.org) -consistent with CERN schedule If actual LARP funding is reduced below planning baseline, timeline and effort must be reassessed, de-scoped, delayed or canceled

Comments from LARP reviewer’s Report June 2013

#4 Is the technical plan proposed by each sub-project optimally developed? Are there additional technical risks that should be considered? Kicker design is still in relatively early stage and several significant issues remain to be investigated and addressed, such as handling beam-induced power and ultra high vacuum requirements. #5 Is the proposed management structure appropriate for the scope and scale of the project? Not presented. #6 Are there additional comments the Committee feels are relevant, regarding either individual tasks or the project as a whole? We suggest exploring collaboration with RHIC, which has similar instabilities for which it is pursuing feedback damping. Installation of a prototype wideband kicker in the SPS before the end of LS1 is critical.

Impacts of FY2014 Funding Reductions

Major events since June 2013 FNAL Review

CERN has slipped LS2 one year ( post LS2 restart now 2020) FY2014 LARP funding reduced by 1.1M$ Feedback Project FY14 funds reduced substantially below guideline plans, with critical impacts on FY14 progress and planned FY15 tasks LARP project funds expected 2017, now delayed

LARP Management has requested re-scoped plans considering

Funding as requested ( LARP June 2013 planning levels), with LARP base continuation in FY17 Funding at 90% levels ( assign 12 - 16% cuts to June 2013 budget plans) Funding at 80% levels ( assign 35% cuts to June 2013 budget plans)

FY15, FY16 goals - with 12 - 16% cuts

First priority - items dropped in FY14 cuts ( Timing/Synch for energy ramp, Orbit offset compensation, matlab tools) Second - augment FY15 MD measurements with wideband DEMO system (SPS beam time and analysis)

Travel funds necessary to do SPS measurements Diagnostic and beam instrumentation techniques to optimize feedback parameters and understand system effectiveness, interaction with existing feedback Evaluate Kicker performance, options ( wideband? dual band?)

Risks and Mitigation

Successful 1 bunch Demo and initial MD effort is excellent start to show ability to meet schedule requirements and technical competence External Technical Reviews - June and July 2013 validate approach and plan towards LS2 full-function system Technical Risks - Uncertainty in required bandwidth, control methods for non-linear system, complexity/type of control algorithm, necessary system power, etc.

Mitigations in reconfigurable FPGA algorithm, scalable power stages, possibility of adding extra kickers or multiple kicker technologies. Confidence from post LS-1 multi-bunch tests, decision point before fab of full-function deliverable

MD program, extensive simulation and modeling effort help estimate high-current operational dynamics from SPS studies pre-LS2

SLIDE 28

timeframes Schedule Manpower Costs Reviews Impacts Risks, Uncertanties and Mitigation Summary and Discussions

Methods to Increase Risk

Demonstrated risk - underfunding of necessary FY13-14 effort

example, FY13 budget plan, underfunding of actual FY13 year limitation of engineering contribution to 12.5% FTE Guarantees project is understaffed in FY14, loses important time this year to work

n critical system capabilities ( energy ramp, multi-bunch capability, etc.) necessary

for post LS1 MD program. M&S funds limited FY14 amplifier evaluation/purchase pushed back into FY15 due to budget limits No new wideband amplifiers in place to drive new kickers Lack of manpower assignment authority means risk of loss of critical signal processing engineer, loss of continuity of project progress ( SLAC management priority isn’t LARP)

Mismatch of LARP funding profile with HL-LHC schedule, CERN anticipation of feedback for use post LS2 Reductions of spending below LARP June 2013 budget plan reduce possible development of all required system features, provide less functional system with incomplete capabilities. Doesn’t meet HL upgrade requirements.

Wideband Feedback - Implementation in LHC

Architecture being developed is reconfigurable! Processing unit implementation in LHC similar to SPS: SPS LHC RF frequency (MHz) 200 400 frev (kHz) 43.4 11.1 # bunches/beam 288 2808 # samples/bunch 16 16 # filter taps/sample 16 16 Multi-Accum (GMac/s) 3.2 8 LHC needs more multiply-accumulation operation resources because of # of bunches, but reduced frev allows longer computation time (assuming diagonal control).

LHC signal processing can be expanded from SPS architecture with more FPGA resources Similar architecture can accommodate needs of both SPS and LHC.

Still need kicker of appropriate bandwidth with acceptable impedance for LHC. Learn from SPS experience.
